我正在使用elasticsearch js client，我想找到wirh attrs.tags==的所有字段并删除该值。更新返回200和1个正确的已更新事件。但当我列出所有事件时，仍然可以看到attrs.tags的旧值。为什么不起作用？即使我等待5分钟给弹性时间来更新它，我仍然得到相同的结果。

async function search() {
        var tag = req.body.tags;
        var client = connectToES(res);
        const response = await client.updateByQuery({
            index: "*",
            type: '_doc',
            body: {
                "query": {
                    "match": {
                        "attrs.tags": tag
                    }
                },
                "script": { "inline": "ctx._source.attrs.tag = ''" }
            }
        });

        client.close();
    }
